Cut out. Lots of us pay for things we do not even use. This is another mistake that gets easier to make with so many automated payment plans. Do you keep a gym membership that you do not use? Replace that with a brisk walk, weights, or a stationary bike. You will not have to make monthly payments, and you may find it is more convenient.
The second thing we need to do is to find out how much money you actually spend each month again include everything even those items that your spouse does not know about like that Latte down at the coffee stand, that you get on a daily basis. It helps to break this down a little. Fixed nonnegotiable expenses, things we actually cannot do without, we all need food lodging medical care basic clothing insurance property taxes a car may be necessary where you live, you get the idea.
